Figured this one out. I was able to get the dialog box to reset back to checked by default by doing the following:
File/Retrieve From/Corporate Documents
Pick a document and check the box
Close the dialog without actually retrieving the document
Next time you go in, it will be checked by default…at least it was for me.
